Python 3.12+ drops optional GIL-free mode

Python is moving towards a no-GIL world, but that does not imply faster execution speed implicitly. Recent Python versions (3.12+ and upcoming 3.13+) are have started to support for an optional GIL-free mode. Python is not removing the GIL overnight though. Instead, it’s preparing for C extensions and existing libraries to adopt this new world. Removing GIL means: -> better CPU parallelism with threads -> but also more responsibility on developers and libraries What this does not mean (for now): -> Async programming is not going away -> Multiprocessing is still relevant It’s fascinating to see how Python evolves; balancing performance, safety and backward compatibility. I am trying to learn Python Internals and its recent changes and will share my learnings. Do follow along and tell your experiences in comments. #Python #PythonInternals #SoftwareEngineering #BackendDevelopment
